Connected Vehicle Pilot Deployment Program
Wyoming (WY) DOT Pilot
Wyoming is an important freight corridor that plays a critical role in the movement of goods across the country and between the United States, Canada, and Mexico. As shown in the figure below, Interstate 80 (I-80) in southern Wyoming which is above 6000 feet is a major corridor for east/west freight movement and moves more than 32 million tons of freight per year. During winter seasons when wind speeds and wind gusts exceed 30 mph and 65 mph respectively, crash rates on I-80 have been found to be 3 to 5 times as high as summer crash rates. This resulted in 200 truck blowovers within 4 years and often led to road closures. Wyoming Department of Transportation (WYDOT) CV Pilot site focuses on the needs of the commercial vehicle operator in the State of Wyoming and will develop applications (see Table 1) that use vehicle to infrastructure (V2I) and vehicle to vehicle (V2V) connectivity to support a flexible range of services from advisories including roadside alerts, parking notifications and dynamic travel guidance. This WYDOT CV Pilot is expected to reduce the number of blowover incidents and adverse weather related incidents (including secondary incidents) in the corridor in order to improve safety and reduce incident-related delays.
WYDOT will develop systems that support the use of CV Technology along the 402 miles of I-80 in Wyoming. As listed in Table 2, approximately 75 roadside units (RSUs) that can receive and broadcast message using Dedicated Short Range Communication (DSRC) will be deployed along various sections of I-80. WYDOT will equip around 400 vehicles, a combination of fleet vehicles and commercial trucks with on-board units (OBUs). Of the 400 vehicles, at least 150 would be heavy trucks that are expected to be regular users of I-80. In addition, of the 400 equipped-vehicles, 100 WYDOT fleet vehicles, snowplows and highway patrol vehicles, will be equipped with OBUs and mobile weather sensors.

Sure hope they don’t track and sell location like the Weather Channel app
Downloading now. Hopeful.
So far WDOT’s twitter feed is the most useful thing.
WDOT’s webpage is really hard to use on an ipad or iPhone. Not sure about the computer but I need it to work on my phone. While I’m stopped at a rest stop with minimal cell data. Roads need better labels for casual non-professional drivers.
I’m really looking for a system to alert me of dangerous weather conditions on the road from Fort Collins to Laramie — that pass can turn nasty in an instant while road conditions everywhere else are fine. There must be a large number of kids and parents and shoppers traveling from Laramie to Colorado. Many are novice drivers.
We’ve used this for years- it’s a lifesaver
This app shows conditions on both local roads and highways. I wish there was a stated color legend, but it’s fairly obvious, and you can click on icons to see current alert and condition posts. Drill down to city streets is great. I notice that I have to reload this app if I have not used it in awhile— like most other apps. It works; an update in graphics would be good, but the actual detailed Hwy department data is indispensable.
The trucker who went astray on the high elevation Beartooth Hwy should have been using this.
Don’t trust this app
Just came from Buffalo to Tensleep. The app had notice of “Commercial Vehicle Testing Operations,” so we called Buffalo DOT Maintenance about expected delays and were assured we’d notice almost nothing. Nowhere on the app nor in our call was the 15-minute wait for a flag car nor the chip and seal operation with loose gravel that went from the Sheep Mountain Lookout Road to the Washakie County line with 45 mph speed limit. Nowhere was the 5-minute wait for flag car along Tensleep Creek with a drop down to mud for a short distance between the end of the canyon and Tensleep. NO INFO. Don’t trust this app. It’s not updated as it should be.

Some roads start to open while WYDOT crews continue to clear others
CHEYENNE, Wyo. (Wyoming News Now) - Some of the roads in Wyoming are beginning to open back up while others remain closed after a winter storm hit the cowboy state. Around 10:00 a.m. on March 15, the Wyoming Department of Transportation sent out an alert that WY230 between the Colorado State Line and Laramie had been open to all traffic, both directions.
However, WYDOT did also say that crews were working to clear drifts on some sections of I-80 that were as high as four to five feet.

Snow returns this Afternoon through Tuesday night
After sending nearly 18.3 million emails and 22.9 million text messages in 2015, the Wyoming Department of Transportation will streamline its notification system in order to spare travelers' inboxes and better manage costs.
The biggest change will be to alert messages. Instead of detailing specific road conditions, alert messages will now tell the recipient the worst case travel impact -- low, moderate or high -- on a given segment of roadway. Messages will include a link to the "By Route" page for those who seek more detailed conditions.
WYDOT will no longer send messages regarding speed limit reductions. Instead, that information can be found online at the highway conditions page or the conditions map.
Further, the department will no longer resend active messages at 6 a.m. and 8 p.m. -- meaning those subscribed only to daytime messages, for example, will have to check another WYDOT information system to learn about alerts issued during the nighttime period.
Closure messages will stay pretty much the same, the only difference being that an opening time will be provided if available.
Earlier this year, WYDOT launched the Wyoming 511 mobile app for Android and Apple phones -- a great way to access up-to-date highway conditions and alerts on demand. The app is designed to provide information throughout your trip with voice alerts as well as pre-trip information via a map.

WYDOT has made another addition to its popular 511 Travel Information Service. The new feature is called "511 Notify," and it allows travelers to receive notifications of road closures and openings as well as certain other travel alerts via email and text messages.
Previously, motorists wanting to check for alerts had to call the 511 system or access the 511 Travel Information Web site (www.wyoroad.info) . Now, they can let the system contact them, reducing the number of times they need to check the 511 system.
Subscribers to 511 Notify will be contacted only with what WYDOT considers critical alerts. Notifications will NOT be made when road or weather conditions change, for example, from dry to slick pavement or when rain or snow begins or ends.
Updates provided by 511 Notify include:
- temporary and seasonal road closures and openings.
- travel alerts such as when the chain law is in effect or no unnecessary travel is recommended.
- Other types of alerts and advisories including reduced visibility, black ice, falling rock, high winds, or no light trailers due to windy conditions.
Subscribers to 511 Notify can customize the alerts they receive by route. For example, someone who drives Interstate 80 frequently can choose to receive alerts for that route only, or for only a segment of that route, such as Cheyenne to Laramie or the Utah state line to Rock Springs.
Further, they can specify to hear all alerts, no matter when they are posted, or only those alerts posted during a certain time period. A commuter could select to receive only reports generated between 6 a.m. and 9 a.m. and then from 3 p.m. to 5 p.m.
Signing up is quick and easy. The only requirement is having an active e-mail account. At a minimum, updates from 511 Notify will be sent as an email to the address listed on a subscriber�s account. The subscriber may also opt to receive alerts at a secondary e-mail address or as a text message to their cell phone.
The service is offered free of charge to the public, although subscribers should be aware that standard text messaging fees apply. Those wishing to subscribe should access the Wyoming Travel Information Service Web site and select "Sign Up to Receive E-mail/Text Updates" located near the bottom of the page.
511 Notify is powered by GovDelivery, a leading provider of government-to-citizen communications. The system delivers messages very quickly so subscribers will know right away when WYDOT posts a travel alert.
511 Notify is intended primarily as a pre-trip information service. Motorists are strongly cautioned not to engage in text messaging while driving.

Her figure deserves special attention - she is absolutely proportionally built. The chest is quite neat, the second and a half size, each breast is like a big apple. Very beautiful athletic legs, smooth healthy calves, thighs are neither thick nor thin. The ass is firm and pleasant to the touch.
